The BriefcasePRO  is equivalent for Yahoo's Briefcase. The user interface is intuitive and uses AJAX for several operations, therefore no page reloads to slow down your work. You can ADD more than one file at a time; number can be set in admin backend. The uploaded Files can be SHARED with one user, more than one user, all users, or with the public (registered and unregistered users). If you uploaded some files in the wrong folder you can always MOVE them as you please. Files can be assigned to several Categories (configurable in the admin backend) and the category can also be changed after the upload. Create Folders where you like, even folder in folder. Logged on as administrator you can access ALL the Files uploaded by all users on your system. You can search after certain terms or filter one particular user. Any file can be deleted, renamed or you can change it's Category.
